Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a moving toy in which a moving object on a rotating stage performs a second movement different from the movement of the rotating stage.

(Prior art and its problems) A rotating stage is provided on the music box,
A music box is known in which a doll is placed on the rotating stage, and the doll rotates together with the rotating stage during performance.

In the case of the above-mentioned music box, the doll simply moves in a circular motion together with the rotating stage, and the movement is monotonous and lacks interest.

The present invention reveals a moving toy in which a doll on a rotating stage performs a second movement different from the rotation of the stage, and can be enjoyed just by looking at it.

(Means for Solving the Problem) In order to achieve the above object, the movable toy of the present invention has a non-circular or eccentric circular guide on the back surface of the rotating stage 4 that surrounds the center of rotation of the stage 4 in an endless manner. A track 41 is formed.

A rotary member 5 is rotatably disposed below the rotary stage 4, and a slide track 51 extending outward from the center of rotation of the stage is formed on the rotary member 5. A rotation device 7 is connected to rotate the stage 4 in the same direction as the stage 4 in the opposite direction or at a different speed from the rotation stage 4.

A slide member 8 made of a magnet or a material that is attracted to a magnet is connected to the guide track 41 and the slide track 5.
1 and is slidably deployed.

A movable object 9 is placed on the rotary stage 4 at a position corresponding to the slide member 8, and the lower part of the movable object 9 is made of a material that is attractive to the slide member 8.

(Operations and Effects) Since the slide track 51 of the rotating member 5 extends outward from the rotation center side of the stage, the slide member 8 slidably engaged with the track follows the rotating member 5. Rotates in the same direction as the member.

Further, since the guide track 41 of the rotation stage 4 is formed in a non-circular or eccentric circular shape, the guide track 41
The slide member 8, which is also engaged with the rotating member 5, approaches and moves away from the center of rotation along the guide track 41 while rotating together with the rotating member 5.

Since the rotation stage 4 and the rotation member 5 rotate in opposite directions or in the same direction at different speeds, the rotation speed of the slide member 8 is different from the rotation of the rotation stage 4.

Therefore, the moving object 9 placed on the rotation stage 4 and attracted to the slide member 8 performs the same movement on the stage 4 as the movement of the slide member 8, which is seemingly unrelated to the rotation of the stage 4, as in the conventional case. Compared to the monotonous movement of the doll rotating together with the rotating stage 4, the movement of the moving object 9 is complex and more interesting.

(Examples) Since the following examples are for explaining the present invention, they should not be construed to limit or reduce the invention described in the scope of the utility model registration claims.

The present invention will be explained below based on an example of a music box.

As shown in FIG. 1, a substantially rectangular box 1 accommodates a music box main body 2 and a pull-out accessory box 11, and a winding screw 21 of the music box main body 2 protrudes through a box wall 13.

A drive spring (not shown) built into the music box body 2 is wound up by the winding screw 21. Furthermore, when the accessory box 11 is pulled out a little, the performance starts, and when it is pushed in, the performance is stopped.

A rectangular substrate 3 is attached to the upper surface of the box 1, and the substrate 3 has a circular recess 31 in the center, and a through window hole 32 is formed in a part of the recess 31.

A rotating shaft 22 protruding from the music box main body 2 passes through the ceiling wall of the box 1 and a through-hole 32 of the board 3 to project upward, and a driving gear 23 is attached to the projecting end.

The drive gear 23 is a two-stage gear with a large gear 23b at the top and a small gear 23a at the bottom.

A circular rotation stage 4 is rotatably arranged within the circular recess 31 of the substrate 3. The rotation stage 4 is disposed concentrically on a driven gear 61 rotatably provided at the center of the substrate 3 via a locking piece 46.

As shown in FIGS. 1 and 2, the locking piece 46 is screwed and fixed to a boss 40 protruding from the center of the back surface of the rotation stage 4, and has three locking legs 47 projecting downward at equal intervals in the circumferential direction. The tips of the legs 47 are bent slightly outward to form retaining pieces 48.

The driven gear 61 is provided with an arc-shaped through hole 62 in which the locking leg 47 is fitted in a circle around the rotation center of the gear 61. Retaining piece 4 with locking leg at one end
An enlarged hole portion 62 into which the hole 8 fits is formed.

If each of the locking legs 47 of the locking piece 46 is inserted into the enlarged hole portion 62 of the through hole 62 of the driven gear 61 and then rotated, the locking piece 46 and the driven gear 61 will not come off.

The driven gear 61 is the small gear 23 of the drive gear 23.
a and constitutes a rotation drive device 6 for the rotation stage 4, and when the drive gear 23 rotates, the driven gear 61 and the rotation stage 4 rotate in a direction opposite to the rotation direction of each drive gear.

A disk-shaped rotating member 5 is disposed below the rotating stage 4 and can rotate freely regardless of the rotation of the stage 4. An annular gear 71 rotates integrally with the rotating member 5 at the lower member of the rotational center of the rotating member 5. Mounted as possible.

The ring gear 71 is connected to the upper cylindrical portion 4 of the locking piece 46.
The large gear 2 of the drive gear 23 is fitted into the drive gear 9 for free rotation and is connected to the intermediate gear 7 which is rotatably supported on the base plate 3.
3b to constitute a rotating device 7 for the rotating member 5.

The rotary drive device 6 of the rotary stage 4 and the rotary device 7 of the rotary member 5 are both inputted from a common drive gear 23, but the rotation speed depends on the tooth ratio of the power transmission gear and the presence or absence of the intermediate gear 72. The rotating member 5 is in the opposite direction to the stage 4 and
rotates faster than.

A groove-shaped guide track 41 and a slide track 51 for guiding a slide member 8 (described later) are formed on the lower surface of the rotation stage 4 and the upper surface of the rotation member 5.

As shown in FIG. 3, the guide track 41 formed on the rotation stage 4 is formed into a non-circular shape, with a small curvature arc groove section 41 passing around the outer periphery of the rotation stage 4 and a large curvature arc groove section 41b passing through the center side of the stage 4. are opposed to each other with the center of rotation of the stage 4 in between, and the ends of both grooves are connected by substantially linear grooves 41c and 41d.

A slide track 51 formed on the rotating member 5 extends in the radial direction.

A circular slide member 8 is disposed astride the guide track 41 of the rotary stage 4 and the slide track 51 of the rotary member 5 so as to be slidable on both tracks, and the slide member 8 is formed of a magnet.

A moving object 9 is placed on the rotation stage 4 at a position corresponding to the slide member 8. The lower surface of the moving object 9 is made of a magnetic metal, such as iron, that is attracted to a magnet.

A decorative ornament 91 is fixedly arranged inside the guide track 41 of the rotating stage 4, and a transparent cover 12 is placed over the box 1. Decorative ornament 9
1 is curved along the guide track 41.

When the accessory box 11 is pulled out, the drive gear 23 rotates clockwise in FIG. 3, and the driven gear 61 of the rotation stage 4, which is directly meshed with the pinion 23a of the drive gear, rotates counterclockwise. Rotates at reduced speed,
The driven gear 61 decelerates and rotates counterclockwise, and the rotation stage 4 on the gear rotates at a reduced speed.
rotates counterclockwise together with the driven gear.

The annular gear 71 of the rotating member 5, which is connected to the large gear 23b of the drive gear 23 via the intermediate gear 72, rotates clockwise at an increased speed.

A slide track 5 extending in the radial direction of the rotating member 5
1 moves in the same direction as the rotating member 5, but the sliding member 8 is also slidably engaged with the guide track 41 of the rotating stage 4, and the guide track 41 It approaches and moves away from the rotation center of the rotation stage 4 in response to the curvature of the rotation stage 4.

Since the moving object 9 on the rotating stage 4 is attracted to the slide member 8 and moves together with the slide member 8, the moving object 9 moves on the rotating stage 4 in a direction opposite to the rotating direction of the stage 4. At the same time, it approaches and separates from the center side of the rotation stage 4.

A decorative ornament 91 is provided in the center of the rotating stage 4, but this ornament is located inside the guide track 41 of the stage 4, and the moving object 9 will not deviate from the guide track 41. The moving object 9 moves in the direction opposite to the rotation of the rotating stage 4 while approaching and separating from the center of the rotating stage 4 while avoiding the decorative ornament 91, making the movement complicated and interesting.

The drawings and the description of the above-mentioned embodiments are for explaining the present invention, and are not intended to limit or reduce the scope of the invention described in the claims of the utility model registration.

For example, it can be modified as follows.

FIG. 5 shows another embodiment of the rotating member 5, in which four slide tracks 51, first, second, third, and fourth, are formed in the radial direction.

The first and second slide orbits 51 and 51a are opposed to each other across the center of rotation, and the second slide orbit 51
Third and fourth slide tracks 51b, 51 on both sides of a
c are formed at an interval of 60° with respect to the second slide track 51a.

When two moving objects are placed on the rotation stage 4, the slide members 8 and 8a are engaged with the first and second slide tracks 51 and 51a, and when three moving objects are placed on the rotation stage 4, the first, third, and Slide members 8, 8b,
8c, the moving objects 9 can be placed on the rotation stage 4 with substantially equal intervals.

Further, even if the guide track 41 of the rotary stage 4 is formed in a circular shape at an eccentric position on the stage, the same effect as described above can be obtained.

Alternatively, a magnet may be formed on the lower surface of the moving object 9, and the magnet and the magnet engaged with the guide track 41 may have different polarities facing each other.

Furthermore, the same effect as described above can be obtained even if the lower surface of the moving object 9 is made of a magnet and a slide body made of a magnetic metal such as iron is slidably disposed on the guide track 41.
